COMBINATION-TOOL.

Specification of Letters Patent.

Patented July 30,1907.

Application filed February 19, 1907. Serial No. 358,295.

To all whom it may concern:

Be it known that I, WILLmM Boorn, a citizen of the United States, residing at the city and county of Donver and State of Colorado, have invented certain new and useful Improvements in CombinatiorrTools; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to improvements in combination tools.

The novel feature of my improved construction consists of means located in the rear of the pivot, for cutting glass tubes. These cutting devices are so arranged that when the jaws of the instrument are closed, the cutters are still separated from the handle located opposite the handle with which they are connected.

The invention will now be described in detail refer ence being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure 1 is an elevation of my improved device shown in the closed position. Fig. 2 is a similar view showing the tool in position for use on a glass tube which is in position for cutting. Fig. 3 is an inside edge view of one member of the tool.

The same reference characters indicate the same parts in all the views.

Let the numerals 5 and 6 designate the two members of the tool which are pivotally connected at 7 in the usual way. This tool is provided with a recess 8 for wire cutting purposes. The jaws 10 forward of the pivot are adapted for use as pliers. Nothing, however, is claimed on the wire cutting or plier feature.

In the rear of the pivot 7, the handle or arm 12 of the member 6 is provided with inwardly projecting bifurcated lugs designated 13 and 14, respectively in which lugs are pivotally mounted cutting disks 15, the said mountings and the disks located therein being sufi iciently separated, to facilitate the cutting of a glass tube 16. Each disk is located between the arms of its bifurcated lug and is mounted on a pivot pin 17. This pin may be either fast in the lug allowing the cutter to rotate thereon; or the disk may be fast on the pin and the latter may be journaled in the lug as may be desired. The arm or handle 12 opposite the part 12, is provided with a recess 18, the axis of the curve extending at right angles to the length of the tool. This recess is preferably curved to conform to thecurve of the glass tube of the water gage size. The are of the curve, however, is immaterial so far as the invention is concerned.

When the device is in use for cutting the tube into proper lengths for water gages, the tube is inserted between the cutters 15 and the curved recess 18, the handle parts 12 and 12 being suitably open for the purpose. The operator then presses on the handle parts in the rear of the cutters and simultaneously turns the place during the cutting operation. It is also evident that this is an important feature since where steel disks are employed for cutting glass, more pressure is required than where diamond cutters are used. By virtue of the special construction whereby the tube 16 is inserted in a position at right angles to the length of the tool,

an excellent opportunity is given for manipulating the tube in a rotary direction for cutting purposes.

Another feature of the device which is believed to be novel, is an inwardly extending projection 19 located at the rear end of the arm 12 and having its free extremity formed quite sharp or pointed. The function of this device, is to dig out the packing in which the water gage is inserted at its opposite extremities.

It will be understood that this tool, or more properly,

the novel features are more particularly adapted for use in renewing the water gages of steam boilers.

Having thus described my invention, what I claim is:

1. A combination tool comprising two members pivotally connected, two separated rotary cutters mounted in the rear of the pivot on the handle portions of one of the members while the other member opposite the location of the cutters, is provided with a curved recess forming a seat for a glass tube disposed between the two members in a direction transverse to their length, whereby the tube may be rotated while held in place causing the cutters to act thereon circuniferentially, substantially as described. 2. A combination tool, comprising two members pivotnll connected, one of the members in the rear of the pivot being provided with two bifurcated lugs, 21 glass cutting disk mounted to rotate between each pair of lugs, the said disks being separated in a longitudinal direction, the other member being provided with a curved recess forming a seat for a glass tube when inserted between the two members in a direction transverse to their length.

In testimony whereof I afiix my signature in presence of two witnesses.
